The poster should be of really high resolution so that we can print it to big sizes without any disortion. Plus, an option to add an independent image because whenever i add any jpeg image it is added to a part which is not enough customisable or movable or scalable.

We’ve updated our export format from JPEG to PNG. We hope this change could help with the issue for now. If you wish to increase the resolution, we recommend to go to Resize > Custom Size and double the pixel dimension.

The team is working on enabling PDF export to support high resolution printing, so please stay tuned!
